6 FAQs about [A container holding solid scandium]
How is scandium produced?
Scandium is produced by reducing scandium fluoride with calcium: The metal has little commercial importance. The major application is expected to be as an alloying element with aluminum since it is a light metal. The combination of high strength and light weight makes Al-Sc alloys suitable for a number of applications.
Are scandium alloys used in airplanes?
The Russian military aircrafts Mig 21 and Mig 29 used aluminum scandium alloys. In Europe and the USA, scandium-containing alloys have been evaluated for use in structural parts in airplanes. Cotton S (2006) Lanthanide and actinide chemistry.
What is scandium used for?
